To all wlw-m t may concern.'

Be it known that l, Francis J. MGLQUGH- LIN, a citizen ot the UnitedStates, residing in Brooklyn, county or' Kings, the State of New York,have invented a certain Improvement in @ne-VVay Exit Gates, ot' whichthe following is a specification.

At fair grounds, places oi public amusement, railway stations, andsimilar localities it is desirable to provide means for convenient exit,so constructed as to preventvunauthorized admittance of thepublie,fwhile making egress as easy as'possible, particularly in rushhours.

For this purpose it has been customary, in many places, to provideturn-stiles so constructed as to yield to pressure in one directiononly, and so constructed as to prevent entrance on the .inwardly movingside of the revolving structure.

One disadvantage of this form of gate is that it must be madenecessarily at leasttwice asy wide as the space available for exit,thereby involving a great waste ot space. Another objection-is that themovable structure is heavy to move and makes a great deal of noise whenused, particularly when a crowd is passing` through. Again, it a personusing the gate is carrying bags or bundles, the horizontal grating setat right angles forms a confining space which Otten occasionsinconvenience, and the bars sometimes catch in the clothing or thebundles of the person passing through.

Turnstiles ot this kind are expensive to build and the mechanism issubjected to continual wear and tear, necessitating repairs andconsequent interruption'ot trailic.

The present invention. relates to a relatively simple and inexpensivestructure, entailing almost no waste of space, and by the use oi whichall ot the above named disadvantages ot the usual. turnstile may beobviated.

Certain preferred vforms ot the invention are illustrated in theaccompanyingy drawings, wherein Figure 1v is a diagrammatic plan view ofa two-door straightaway form ot the improved gate, Figure 2 is a similarview oi" a two-door gate presenting a right angled turn, and Figure 3 isa similar view ot' a two-door gate presenting a reverse turn.

In its simplest form the invention comprises a door l0 made just wideenough to allow one person to pass at a time, and adapted to be openedonly from the inside Y outer end of' such 1920. serial no. 375,719.

and by a movement outward only, `as shown by the dotted line at` eachdoor. Such a door is combined nitlrenclosing walls orfences ll, l2,forming a passage on the outside just inea-i5 wide enough tor oneperson, and suliciently long to prevent anyone reaching in from theonen.

The door isarrangedto close automatically in any well known manner, asby the use of aclosing spring 1.3, or equivalent means. lt the movableedge of the door is made to close flush with the wall or jamb so that itcannotbe pulled open from the outside, this will sutlice, but it ispreferable to have a latch lotsome kind on the inside so arranged thatit cannot be operated from the outside of thedoor.

It will be clear from thisdescriptionthat any person passing outwardthrough the door 10, as indicated by the arrow, must lea-vevthe passagebetween the walls l1 and` l2 before time, the door will have been closedautomatically, preventing entrance.

passage to hold the door.

an outsider can enter, and, by that The only possibility 'of defeatingthe `endv Y in `view, with the combination thus tar described. would be`found in collusive action. That is to say one person within might openthe door for anotherwho had come inward `toward it, thus admitting thelatter.

ln order toy prevent this, it is preferred to embody the inventionin'the two-door forni shown in three Aarrangements in the drawings. I A iy' ln this form, the walls lll and l2 are prolonged to a second door l5,similar to the door l0, and preferably provided with' a closing device`Walls 18 and 19 may or may not be used outside oft the second door l5,to torm a narrow passage shown.

l'n Vliggure l the door l5 is parallel to the door 1 0; but if desiredthe second door may be at right anglesl as at 20, in Figure 2, or at anyother angle tothe vdoor 10.

In Figure 3, is showna Vform in which the narrow passage outsideot theiirst door makes a turn throughtwo right angles, the second door 2lopening in rection from the door y10.

l/Vhile it is 16 and an interior latch 17.'

105,y the opposite dipreferred to arrange the-door or doors toonen'outward, as shown, this is lIt will he seen that one of theadvantages of the invention is that, if desired, it can be vused as anentrance, by merely a-stening v bach all of the doors.

in times of einen gency this entre capability takes on consiclernbleimportance.
